Terabase Terafab Solar Construction Automation

Terabase Energy, headquartered in Berkeley, California, applies robotics, AI and software to utility-scale solar construction. Its lineup covers PlantPredict energy modelling, Terafab construction automation, Construct management software and SCADA with plant controls. The company reports more than 200 million USD raised from backers including SoftBank, Breakthrough Energy Ventures and Fifth Wall.

Terafab is an automated field factory that pre-assembles modules onto tracker torque tubes in-line with quality inspection, after which rovers carry the assembled tables to installation points. A single V2 line is reported to reach 2-minute cycle times, above 20 MW installed per week. The first generation has been deployed on five power plant projects.

• Automated table assembly: modules are pre-assembled onto tracker torque tubes in a field factory.
• In-line quality control: module inspection is built into the assembly line.
• Modular footprint: V2 has a smaller footprint for projects of different sizes.
• Digital integration: connects with Construct for digital twin, drone progress tracking and punchlists.
• Rover delivery: rovers carry assembled units to installation points.
• Patents: the company reports granted and pending patents on the system.

EPC contractors building large ground-mounted solar plants with single-axis trackers in the region. Developers evaluating construction automation to shorten schedules on gigawatt-scale pipelines. Owners using the Construct module for digital quality control and progress tracking during construction.

Vendor claims installation productivity up to twice that of traditional stick-build construction. In-line module quality inspection reduces defects before installation. Smaller footprint and modular design suit projects of different sizes. Less manual lifting of heavy glass and steel improves site safety.

Solar construction is constrained by labour availability and installation speed, which drives interest in construction automation for large plants. Vietnam and Southeast Asia are expanding utility-scale solar and face similar workforce and schedule pressure, though Terabase reports its deployments mainly in the United States.
